- the left and right video signal control unit 120 alternately outputs the left and right video signals to alternately display the right eye image R and the left eye image L on the liquid crystal display panel 134.
- the left and right video signal control unit 120 also performs conversion such that the same signal continues twice for each of the right eye video signal and the left eye video signal to perform writing two times, which will be hereinafter described, based on the input left and right video signals.
- the right eye video signal and the left eye video signal converted by the left and right video signal control unit 120 are input to the timing control unit 126.
- the timing control unit 126 converts the right eye video signal and the left eye video signal, which are input, to signals to be input to the liquid crystal display panel 134, and generates a pulse signal used for the operation of the gate driver 130 and the data driver 132.
- the signals converted by the timing control unit 126 are input to the gate driver 130 and the data driver 132, respectively.

- the left and right video signal control unit 120 sends a timing signal indicating the timing of switching of the right eye video signal and the left eye video signal converted such that same signal continues twice.
- the shutter control unit 122 sends a drive signal for causing the emitter 126 to emit light to the emitter 126 based on the timing signal sent from the left and right video signal control unit 120.
- the emitter 126 transmits an optical signal indicating the timing of switching of the left and right video signals to the viewing eyeglasses 200.
- the displayed image viewing eyeglass 200 includes a sensor for receiving the optical signal, of which detailed explanation will be omitted.
- the viewing eyeglasses 200 that received the optical signal alternately performs the opening and closing operation of the liquid crystal shutters 200a, 200b in synchronization with the timing of switching of the right eye video signal and the left eye video signal of the image display apparatus 100.

- FIGS. 3A and 3B are timing charts showing the timing of the left and right video displays and the opening and closing of the liquid crystal shutters 200a, 200b.
- the right eye image R and the left eye image L are alternately displayed in the image display apparatus 100, but flicker (flickering of screen) occurs if the drive frequency at which one frame of the right eye image R or the left eye image L is displayed is lower than or equal to 60 [Hz].
- flicker flickering of screen
- FIGS. 3A and 3B a case in which one frame of the right eye image R or the left eye image L is displayed at 120 [Hz] is shown in FIGS. 3A and 3B .
- each of the right eye image R and the left eye image L is displayed at the drive frequency of 120 [Hz]
- the display is normally performed line sequentially from one end to the other end of the screen.
- the display on the liquid crystal display panel 134 is sometimes referred to as writing of display data to the liquid crystal panel 134.
- the display is performed line sequentially from the upper side to the lower side on the screen in the liquid crystal display panel 134. Therefore, the time at which the display of the right eye image R starts becomes later than t0, and the time at which the display of the right eye image R is finished becomes later than t1 towards the lower side.
- the response speed of the liquid crystal is relatively slow when the display is performed line sequentially. Therefore, for the writing of the right eye image R, the writing eventually starts at the lower side of the screen at the time t1 at which the desired luminance is achieved at the upper side of the screen. For the writing of the left eye image L as well, the writing eventually starts at the lower side of the screen at the time t3 at which the desired luminance is achieved at the upper side of the screen.
- FIG. 3B shows the opening and closing timing of the liquid crystal shutters 200a, 200b.
- the liquid crystal shutter R for the right eye (liquid crystal shutter 200a) is opened between time t1 to t10, and between time t5 to t12.
- the liquid crystal shutter L for the left eye (liquid crystal shutter 200b) is opened between time t3 and t11, and between time t7 and t13.
- the display of the right eye image R is finished and the next left eye image L is displayed while the shutter 200a is opened.
- the left eye image L of the next frame is displayed between time t1 and t10.
- the liquid crystal may not sufficiently respond as the liquid crystal shutter 200a is opened immediately after the display starts at time t1.
- the present embodiment adopts a method of increasing the drive frequency of the liquid crystal panel, and double displaying (writing) one frame of left and right images on the liquid crystal display panel 134.
- FIGS. 4A to 4C are timing charts showing the principle of writing two times and the opening and closing of the liquid crystal shutters 200a, 200b according to the present embodiment in a case in which the right eye image R and the left eye image L are respectively displayed at the drive frequency of 240 [Hz].
- FIG. 4B shows a state in which the backlight 136 of the liquid crystal display panel 134 is emitting light. In the example shown in FIG. 4B , the backlight 136 is lighted on a constant basis.
- FIG. 4C shows the opening and closing timing of the liquid crystal shutters 200a, 200b, similar to FIG. 3B .
- the left eye image L written between time t20 and t21 and the left eye image written between time t21 and t22 are basically the same image, but may differ due to adjustments such as overdrive processing and the like.
- a predetermined blank period may be provided between the left eye image L written for the first time and the left eye image L written for the second time.
- the right eye image R is written after the left eye image L is written twice.
- the right eye image R written between time t22 and t23 and the right eye image written between time t23 and t24 are basically the same image, but may differ due to adjustments such as overdrive processing and the like.
- a predetermined blank period may be provided between the right eye image R written for the first time and the right eye image R written for the second time, or between the left eye image L and the right eye image R.
- the response time of the liquid crystal display device is relatively slow, and thus each pixel does not achieve the desired luminance if the writing time is a short time.
- the right eye image R and the left eye image L are respectively written twice, and thus the desired luminance can be held at the time of the second writing, and a state in which the desired luminance is reached at both the upper side and the lower side of the screen can be realized.
- the luminance of the left eye image L reaches the desired level in the entire region from the upper side of the screen to the lower side of the screen. Therefore, as shown in FIG. 4C , only the left eye image L is visually recognized by the left eye of the user and the occurrence of crosstalk can be reliably suppressed by opening the liquid crystal shutter 200b only for a predetermined period (e.g., 2.1 ms) having the time t22 as the center.
- the crosstalk and the luminance are in a trade-off relationship, so that the shutter-open period can be appropriately set depending on which to prioritize.
- the luminance of the right eye image R reaches the desired level in the entire region from the upper side of the screen to the lower side of the screen. Therefore, as shown in FIG. 4C , only the right eye image R is visually recognized by the right eye of the user and the occurrence of crosstalk can be reliably suppressed by opening the liquid crystal shutter 200a only for a predetermined period (e.g., 2.1 ms) having the time t24 as the center.
- a predetermined period e.g., 2.1 ms
- the desired luminance is not reached at the lower part of the screen at the end of writing in the first writing if the drive frequency of the liquid crystal is increased, and thus the liquid crystal shutters 200a, 200b are closed in at least one partial interval at the time of first writing, during which the liquid crystal display panel 134 is in the state of the transient response. More specifically, the liquid crystal shutters 200a, 200b are closed in the interval of 4.2 ms corresponding to at least 50% of about 8.4 ms during which the right eye image R or the left eye image L is displayed. Thereby, it is possible to avoid that the video present at the time when the liquid crystal display panel 132 is in the state of the transient response due to the first writing is not visually recognized by the user.
- the liquid crystal shutter R for the right eye (liquid crystal shutter 200a) is opened only for a predetermined time (2.1 ms) having the time t24 as the center.
- the liquid crystal shutter L for the left eye (liquid crystal shutter 200b) is opened only for a predetermined time (2.1 ms) having the time t22, t26 as the center.
- the second writing of the right eye image R starts at the lower side of the screen, and the second writing of the right eye image R ends at the upper side of the screen. Therefore, the right eye image R by the first writing is not visually recognized by the right eye of the user by opening the liquid crystal shutter 200a at the time point of time t24, and the right eye image R by the second writing is visually recognized by the right eye of the user in the entire region from the lower side to the upper side of the screen.
- the second writing of the left eye image L starts at the lower side of the screen, and the second writing of the left eye image L ends at the upper side of the screen. Therefore, the left eye image L by the first writing is not visually recognized by the left eye of the user by opening the liquid crystal shutter 200b at the time point of time t22 or time t26. The left eye image L by the second writing is thus visually recognized by the left eye of the user in the entire region from the lower side to the upper side of the screen.
- the liquid crystal shutters 200a, 200b are opened only in one partial interval in which the right eye image R or the left eye image L written for the second time is displayed in the entire screen.
- the user thus can visually recognize the video in which the desired luminance is reached by the second writing. Therefore, at the time points of t22, t24, and t26 shown in FIG. 4C , the occurrence of the crosstalk can be reliably suppressed by opening the liquid crystal shutters 200a, 200b only for a predetermined minimum time (e.g., 2.1 ms).
- FIGS. 5A to 5C are timing charts showing a state in which the opening and closing of the liquid crystal shutters 200a, 200b and the lighting of the backlight 136 are synchronized.
- FIGS. 5A and 5C are similar to FIG. 4A and FIG. 4C .
- the leak light which has a value obtained by multiplying the transmissivity in the closed state of the liquid crystal shutter and the luminance of the liquid crystal display panel 134, is transmitted through the liquid crystal shutters 200a, 200b during the period in which the liquid crystal shutters 200a, 200b are closed.
- the backlight 136 is lighted in synchronization with the opening and closing of the liquid crystal shutters 200a, 200b in the present embodiment.
- the liquid crystal shutter 200b is opened between the time t40 and t41, and the backlight 136 is lighted between the time t30 and t31 in synchronization with the opening and closing of the liquid crystal shutter 200b.
- the interval from the time t40 to t41, during which liquid crystal shutters 200b is in the open state is set to be sufficiently longer than the interval from time t30 to time t31 during which the backlight 136 is lighted.
- the liquid crystal shutter 200a is opened from the time t42 to t43, and the backlight 136 is lighted from the time t32 to t33 in synchronization with the opening and closing of the liquid crystal shutters 200a, 200b.
- the liquid crystal shutter 200b is opened between time t44 and t45, and the backlight 136 is lighted between time t34 and t35 in synchronization with the opening and closing of the liquid crystal shutter 200b.
- the interval from time t42 to t43, in which the liquid crystal shutter 200a is in the opened state is set to be sufficiently longer than the interval from time t32 to t33 in which the backlight 136 is lighted.
- the interval from time t44 to t45 in which the liquid crystal shutter 200a is in the opened state is set to be sufficiently longer than the interval from time t34 to t35 in which the backlight 136 is lighted.
- the open period of the liquid crystal shutters 200a, 200b is sufficiently long compared to the case of FIGS. 4A to 4C .
- the open period of the liquid crystal shutters 200a, 200b is short or 2.1 ms, and thus the ratio of the transient period in which the liquid crystal shutters 200a, 200b respond becomes high with respect to the open period. Assumption can be made that the transmissivity of light may not be sufficiently ensured in the open period.
- the open period of the liquid crystal shutters 200a, 200b is set to be sufficiently long, and the backlight 136 is lighted at the timing the liquid crystal fully responds by the second display and the transmissivity becomes sufficiently high.
- the lighting period of the backlight 136 corresponds to the open period of the liquid crystal shutters 200a, 200b shown in FIGS. 4A to 4C . Therefore, a user can visually recognize the left eye image L when the backlight 136 is lighted between time t30 and 31, and can visually recognize the right eye image R when the backlight 136 is lighted between time t32 and t33, and between time t34 and t35.
- the backlight 136 is not lighted or emits light in dark color such as gray in the interval other than between time t40 and t41, between time t42 and t43, and between time t44 and t45.
- the backlight 136 is desirably lighted in dark color such as gray without being fully unlighted even in periods other than the lighting period of the backlight 136 when using the liquid crystal that does not have sufficient response property toward the usage temperature since the response property of the liquid crystal depends on the temperature. Thereby, it is possible to prevent the temperature of the backlight 136 and the liquid crystal display panel 134 from lowering in periods other than the lighting period, and to reliably suppress the lowering of the response property of the liquid crystal.
- the backlight 136 is lighted in accordance with the timing at which the liquid crystal shutters 200a, 200b open, and the luminance of the backlight 136 in other intervals is lowered. Therefore, the contrast can be further enhanced in the opened state and the closed state of the liquid crystal shutters 200a, 200b, and the user can visually recognize the right eye image R or the left eye image L only in the interval the backlight 136 is lighted.
- the transmissivity of light in the shutter opened state slightly lowers due to the transmissivity of the liquid crystal.
- the leak light is transmitted through the liquid crystal shutters even in the shutter closed state.
- the contrast of the opened state and the closed state of the liquid crystal shutters may not be sufficiently increased.
- the luminance of the video lowers in the shutter opened state, and the occurrence of crosstalk by the leakage light in the shutter closed state becomes a matter of concern.
- the open period of the liquid crystal shutters 200a, 200b is set to be sufficiently long, and the backlight 136 emits light after the liquid crystal shutters 200a, 200b fully respond and are in the opened state. Therefore, the luminance of the video visually recognized by the user can be sufficiently increased in the opened state of the liquid crystal shutters 200a, 200b.
- the luminance of the backlight 136 is lowered in the intervals other than between time t30 and t31, between time t32 and t33, and between time t34 and t35.
- the luminance of the backlight 136 is increased only in a predetermined interval in synchronization with the opening and closing of the liquid crystal shutters 200a, 200b, and hence it is possible to cause the luminance at the timing of lighting to be higher compared to that when the backlight 136 is lighted on a constant basis in the two-dimensional image display.
- the luminance of the backlight 136 is increased only in a predetermined interval, it is possible to reserve the lifespan (durable years) equivalent to that when the backlight 136 is lighted on a constant basis, even if the luminance at the time of light emission is further increased.
- the configuration of the present embodiment it is possible to cause the luminance at the time of lighting to be higher than that when the backlight 136 is lighted on a constant basis, and the contrast of the liquid crystal display panel 134 in the opened state and the closed state of the liquid crystal shutters 200a, 200b can be further enhanced.
- the lack of contrast of the liquid crystal shutters 200a, 200b is compensated by the contrast of the backlight 136. Therefore, the user can visually recognize the desired video with a high luminance obtained by the light emission of the backlight 136 in the shutter opened state, and thus video without crosstalk due to lowering of the luminance of the backlight 136, can be visually recognized in the shutter closed state.
- the writing of two times and the synchronization between the backlight 136 and the opening and closing of the shutter are simultaneously used, but the occurrence of the crosstalk can be suppressed and the desired luminance can be achieved even when only the synchronization between the backlight 136 and the opening and closing of the shutter is performed without performing the writing of two times.
- FIGS. 6A to 6C are timing charts showing a state in which the opening and closing of the liquid crystal shutters 200a, 200b and the lighting of the backlight 136 are synchronized, and show a case in which the backlight 136 is scan lighted.
- FIGS. 6A to 6C FIGS. 6A and 6C are similar to FIGS. 5A and 5C .
- FIGS. 5A to 5C taking the interval t40 to t41for example, in which the liquid crystal shutter 200b is opened, the entire surface of the backlight 136 is lighted in the interval between t30 and 31.
- the backlight 136 is scan lighted from the upper side of the screen to the lower side of the screen in the interval between t40 and t41 during which the liquid crystal shutter 200b is opened. In other words, as shown in FIG.
- the backlight 136 is lighted for the interval T which is shorter than the interval t40 to t41, and the interval T in which the backlight 136 is lighted is moved from the upper side of the screen to the lower side of the screen in the interval t40 to t41.
- the occurrence of crosstalk can be suppressed since the liquid crystal shutters 200a, 200b are opened with the liquid crystal responding by writing each of the right eye image R and the left eye image L twice.
- the backlight 136 is scan lighted while the shutters 200a, 200b are opened, and hence the occurrence of crosstalk can be more reliably suppressed.
- a region A1 at the upper side of the screen shown in FIG. 6A shows a state of transition when switching from the left eye image L to the right eye image R. Therefore, the right eye image R may slightly mix to the left eye image L around the timing at which the liquid crystal shutter 200b closes.
- the backlight 136 is not lighted at the upper side of the screen at the timing related to the region A1.
- the right eye image R is not lighted by the backlight 136. Therefore, it is possible to reliably prevent the right eye image R from mixing to the left eye image L.
- a region A2 at the lower side of the screen in the neighborhood of the interval t30 to t31 which is shown in FIG. 6A , shows a state of transition when switching from the left eye image L by the first writing to the left eye image L by the second writing.
- the backlight 136 is not lighted at the lower side of the screen at the timing related to the region A2.
- the left eye image L obtained by the first writing is not lighted by the backlight 136 in the region A2 at the lower side of the screen. Furthermore, when the left eye image L by the second writing is displayed at the lower side of the screen, the left eye image L by the second writing is lighted by the scan lighted backlight 136. Therefore, the left eye image L by the second writing can be reliably visually recognized by the user at the lower side of the screen. Further, it is possible to reliably prevent the left eye image L by the first writing, to which the liquid crystal does not yet fully respond, from being visually recognized by the user at the lower side of the screen.
